Profiling

Sires,

I've chosen Scheme48 as one of implementations of Scheme to evaluate some
scheme code I'm developing. I didn't found any reference to a profiler for
Scheme48, although I've found references to a tracer. Is such profiling tool
available? If so, where can I find any references to it?

Thank you in advance.
